As Thomas suggested, improve that by listing the licenses. According to
the LICENSE file, everything is MIT unless the setup.py of each module
says something different, so I have done a quick check:

$ find micropython-lib-v0.5/ -type f -name "setup.py" -exec grep license
{} \; | sort -u
      license='MIT',
      license='Python',

So I think it would be enough by just having:

MICROPYTHON_LIB_LICENSE = Python (some modules), MIT (everything else)

Thomas, what do you think?

It will not harm to add $(TARGET_MAKE_ENV) before $(MAKE) here as well.

This comment, are you trying to keep the lines 80 characters long? In
that case, you can put "don't" in the first line.
